WINDOW-CLEANER APPLIANCE.

`Applicati'mn led March 9 This invention relates to an improved windowcleaner appliance, and an object of the invent-ion is to provide, in adevice of this character, a reciprocating member or rod and a casingtherefor containing an electrical operating means operatively connectedwith the reciprocating member or rod for imparting movement to thelatter, said reciprocating member or rod adapted to carry on itsextremity-an implement for cleaning a window, more especially showwindows and the like.

Another purpose. is to provide a plurality of implements, by which awindow may be washed or mopped, wiped and finally polished, there beingthe provision of means on said implements common to them all forattaching them individually to the end of the reciprocating member orrod.

Still another purpose is to provide a polishing implement which includesa base with a rubber facing, against which a chamois skin or leatherpolisher engages, the polisher being transferable from one roller toanother (which rollers are carried by the base of the implement) so asto change the polishing surt face of the polisher when applying the finishing touches to the window. p

A further purpose is to provide a handle. for the casing (which carriesthe operating mechanism), said handle adapted to include several tubularconnectors between the casing and the handle, the connectors being ofdifferent lengths, so as to provide handles Cil ' stance, in cleaning alarge window a long handle would be necessary to reach the top of thewindow, and then as the cleaning process merges toward the bottomshorter handles are necessary.

A still further for holding the of differentlengths for the casing. Forin? 1927. 'sei-iai No. 173,990.

and combination of parts to be hereinafter set forth, shown in thedrawings and claimed.

In the draivings:

Figure 6--is a view showing the manner of attaching the mop or brush tothe endof the reciprocating member or rod.

Figure 7-is a View showing a wiper attached to the end of thereciprocating member or rod.

`Referring to the drawings: 1 identifies a casing, in which is mountedan electric motor 2 the o eratine' shaft of which is mounted in suitablebearings lonthe interiorof the casing. This shaft 3 carries a pinion 5nicshing with a gear (i having its shaft 7 mounted in bearings 8 on theinterior of the casing. A suitable door 9 is hinged at l() to the casingl, and is provided for the purpose of permitting access to the interiorof the casing for making any repairs to the electric motor or gears, orto `a connecting rod or pitman 1l. This pitman 11 is eccentricallyconnected or pivoted at 12 to the gear 6 and in turn pivotally connectedat 13 to a rod 14, `which operates through ball bearings 15 positionedwithin a tubular extension 16 of the ci `sing- 1. The eX- posedextremity of the reciprocating rod or member 14 carries either the mop,washer or scrubber, the wiper or the polishing implement.

The casing l. has a tubular extension 17 at its other end, whichinteriorly carries wires 18 extending from the motor to a conventionaltype of switch 1.9, and the wires from the motor to an approved type` ofplug Q0. These latter' wires 2l as well as the wires-18 are encased in asuitable casing orinsulator;

' tra-l ears" and the openings The tubular extension 17 operativelyconnects with a handle 22 by means ot' a tubular connector 23. Theopposite ends of the connector 23 have ybayonet slots 24 and 25, whichengage with pins 26 and 27 of the handle 22 andtthe tubular extension 17.Y

The exposed end of the reciprocating member or rod terminates in a fork28 the prongs `of which have a transverse connecting bar 29 and also atransverse connecting tube 30. The tube 3() connects the extremities ofthe prongs,while the bary 29 connects the prongs adjacent where theymerge into the rod 14.

.Referring to Figure 3 in particular a holder 311 having a polishingmember 32is provided. 1 This holderconsists of a wooden base 33 which.has a rubber facing 34',`and secured to the Ybase 33 are side plates 35.These side plates have ears 36' provided with openings 37 and 38, theopenings 37 being in the ceni 38 beingformed in the endl ears.V Suitablerollers with relatively large flanges are positioned between the endears of; the holder; The rollers 39 and 40 have their cores hollow, andconnecting the rollers isa chamois skin or leather polishing member 41.This member 41 is adapted to be rolled romone rollerto the other, inorder to change rits face which may contact w-ith the Window to bepolished. VSui-table leaf springs 42 are secured at 43 to the woodenbase of the holder, and the extremities of the leaf springs bear againsttheV face of the chamois skin or leather which is wound about therollers, thereby acting to keep the rollers ,n from turning, .when thepolisher is in action on the face of the window.

Secured to the. side plates are leaf springs `44 having knobs or plugs45, which engage through the openings 37 and 3S ofthe vears,36.- Theseknobs or plugs not only pass through the openings 37 and 38, but alsoextend telescopically into theV tubular cores of the rollers and thetubular connecting rod 30.

The knobs or plugs of the central springs 44 connect the holder to theprongs 28, while the plu s or knobs of the end leaf springs 44 extendinto the cores of the rollers to journal the latter in position.` Plates46 are secured tothe springs 44 and engage through slots 47 intheplates, Yand the lateral ends o'f the plates 46 act to limit the lateralmovement of the v pass through leaf springs 44 by preventing them frombeing moved outwardly too far, when extricating. the plugs or knobs fromthe the rollers vor ,from the tubular rod 30.

Asshown in Figures 6 and 7 there is a mop or scrubber and a wiperdisclosed. Each of these is provided with ears 43, which engageexteriorly of the prongs 28 at their extremities, and carried by theears are leaf springs 49 provided with plugs or knobs 50, which openings51 in the ears and into thetubular rod 30, for the purpose oconnectingthe'mop, brush or scrubber, or the Wiper to the fork of thc rccprocablerod or member 28. Y

A suitable device 52 is provided for holding the mop or scrubber, andthe wiper at any desired angle, according to the position of the 'ocasing which carries the operating mechanism for the rod.

In cleaning windows it is the purpose to lirst attach the mop, scrubberor similar device between the prongs 28, and after thoroughly washingthe window, the scrubber or mop is removed and the wiper in Figure 7substituted, the manner of attachment being the same as that with themop or scrubber. After wiping the window it may be polished, by removingthe wiper and attachin" the chamois skin holder, the attachment ci thisbeing accomplished in the samemnnner as the attachment of the wiperorthe mop or scrubber. The casing 1 with its two tubular extensions 16 and17 may be positioned at the desired angle, and by operating the buttonswitch 19, the electric motor may impart movement to the gear 6, whichwill transmit its rotary movement to a reciprocating movementtransmittedto the member or rod 1.4.

1, and by causing the motor to operate the rod or member 2S willreciprocate carrying the wiper or brush, or the polisher backwards andforwards over the lace of the window.
